currently, i have a pro-chamber mid pipe with 40 series Flowmasters that are dumped. when my rpms are below 2500 the drone is horrendus. I know once I get tailpipes put on it will help a little, but it will still be there. If I were to go with an X-pipe instead, would that help get rid of some of the drone? if so, anybody wanna trade?

nah buddy it's the flowmasters. They are great mufflers for cruising and old muscle cars.... I have the stock H pipe with flows and it drones like you describe.

From what I understand magnaflow are better for no drone... and also if you want even more loudness glasspack style are better (like loud mouth)

If you want no drone in cruising, get the Steeda/Borla catbacks.. they are tuned to tone out drone, I dont understand the science, but I know it works (Ive got a o/r prochamber with steeda/borla catback)

It's called destructive interference. By changing the shape/material/support points, you can get it to resonate with or against the sound waves. If it's with, they add together (constructive), if it's against, they subtract from one another (destructive). Destructive interference is how noise canceling headphones work.
